Did you like the series Drifters?
Would you like to watch some more Drifters?

If you answered yes, then you probably should watch this OVA/Specials/Extra Episodes/whatever. It's largely more of the same, continuing the story and revealing more things about certain characters, particularly the main villain. The story still doesn't reach a conclusion and just kind of abruptly ends. But if you just want more Drifters, here it is.

And if you didn't like Drifters...

Then don't watch this. You probably won't enjoy this either. Or give it a try anyway, you crazy lunatics.
